The Tunguska Event
from Quiet Files · host Meschelle
On the morning of the thirtieth of June, 1908, the sky above central Siberia tore open. An explosion equivalent to ten to fifteen megatons of TNT — a thousand times more powerful than the atomic bomb dropped on Hiroshima — knocked down eighty million trees over an area larger than the city of London. The shockwave circled the Earth twice. For nights afterward, the skies above Europe and Asia remained bright enough to read a newspaper at midnight.When Soviet scientists finally reached the epicenter, nineteen years later, they expected to find a crater.There was no crater.There were no meteorite fragments.This is the story of the Tunguska event — the largest impact event in recorded human history. The nomadic Evenki herders who watched the sky split. The 1927 expedition that found a radial pattern of flattened trees stretching to the horizon, and a center that had no hole. The theories that have come and gone — comet, asteroid, antimatter, black hole, alien spacecraft. And the question that astronomers still cannot definitively answer: what hit the Earth that morning, and how lucky were we that it landed where it did?Episode Fourteen of The Quiet Files.Sources: Leonid Kulik expedition reports, 1927–1939 (Russian Academy of Sciences); Christopher F.
